The invention Will bei fully und erstood from Patented Jen. 9, 1966.

provided With circumferential grooves l, en exterior solls.y in, having transverse socket-s n in its inner side, ein exterior shoulder p, and :in exterior tin-eed g, ell clearly sliown in Fig. l.

Against the shoulder p of the box B is er@ ranged e removable Washer C, lieving tfonsverse sool-:ets n in its inner side, while engag-ed. with the thro-ed g of the box is e nut l), having e reduced and threaded inner end f. @n seid end 'i' oi the nut D is on interiorlythreaded Washerlil, between which and the free vertical movement of the seid. casing' with respect to the box B. Tl flexible bellows-like wel] G surrounds and eonneeted to the ring F endlies it's outer edge suitebl)T connected to the ringfol tlie casing A.

H is en annuler snell, preferably of steel,V

.vliiel'i is arranged Within ond close to the eiroulor seotion a oi the easing A end is connected with the seid easing, preierfibl i through the medium of keys l, disposed in meeting' grooves in tbe sbell ond easing.` The'seid shell H is provided with a. circuler series of interior tents or projections s, which are zirrenged in e vertiesl pleno adjacent to the inner end of tbe easing end are designed for e purpose presently set forth.

K is en onnulus arranged Within the shell li and heving ball-reces if in its outer side. l; L nre entifrietiomlmlls arranged to move in seid inoesl and interposed between the xmnulus K and the shell H, so es to enable the latter to freely turn eroundnpon the former.

M is a sleeve surrounding the outer portion of the box E, N N ontilrietion-bolls nrrenged in the grooves l of the box sind interposed between tbe box end the sleeve M, and l? i 'coiled spring surrounding the sleeve M sind connected et its inner end to tbe seid sleeve end et its outer end to the ennulus K..

The purposeo' the seid coiled spring P is to revent the transmission of shook and jar 'rom tbe easing A to the box B, while in no wey interfering with the rotation oi the eosing A end tbe box l with tbe veliielenxle on which the box is secured. Y

Q are springs arrange-d :ilongsde of tbe IOAO spring P and designed to assist the latter spring in preventing the transmission of shock and jar from the casing A to the box B. These springsQ-are identical in construction, and therefore-a detailed description of the oneshown in Fig. 23 will sufiice to impart a delinite understanding ot' all. The. spring Q, Fig. 3, portion u, its outer end to receive one of the teats s of the shell H, an auxiliarycurved portion QU, eX- tending outwardly from a bight :c at the inner end of the main portion u, and lateral trunnions i, extending from the said bight and disposed in the sockets n 'n' of the collar m and washer (l, respectively, as shown in Figs. l and From the foregoing it follows that in the event el" power being applied to the casing A to rotate the wheel, of which the hub forms a part, the springs Q will serve to transmit rotary motion from the said casing A to the box B and at the saine time will prevent traiisniission ol' shock and jar to the box B and the vehicle in the event ot the casing being suddenly turned, as when a motor-vehiele is started.

R is a circular plate interposed between the outer end of the box B and the wall (Z of casing A and having a central projection .e let into a socket in the outer end of the said box B. This plate lt is designed to prevent the outer end oi the box B and the outer end ol the sleeve M l'roni contacting with the outer wall d ol' the casing.

Notwiti'istanding the practical advantages which we lia-.e hereinbelore ascribedto our novel wheel-hub it will be apparent that the hub is simple and inexpensive and is well adapted to withstand the shocks and strains to which wheel-hubs, particularly those used on the rear axles of motor-vehicles, are ordinarily subjected.

We have specifically desciibed the construction and relative arrangement ol the parts embraced in the present and preferred embodiment olV our invention in order to nnpart a deiinitc understandingr of the said einbodiment. understood as conl'iiiing ourselves to the said specilic construction and relative arrangenient of parts,l as such` changes or modilications may be inade in practice as fairly fall i within the scope of our invention as claimed.
